Basically, X is reload. B is melee. It refers to a quick cancel that allows you to cancel the rest of the melee and reload animations with the BR. Bxb was a double melee that could be done faster than two melee. Bxr would basically be an immediate kill due to the crosshairs being over a guys face when meleeing. The net effect was a shot immediately after hitting the punch.

I normally would've just passed this off as a minor bug. But this has happened to me three times now. All with different weapons (DMR, then BR, then AR) and at completely random times. It has only happened on Exile, however.

I've encountered some other interesting bugs, one of them I know saved on film, but haven't checked the other.
The first seems to happen after a host migration. When the game is up and running again, and I'm back on the ground, I can't seem sprint or even use my armor abilities; even the icon for it is gone. I've had this happen to me a few times.
The second is the strangest yet, and I'm not even sure how it was triggered. I was playing on Exile, and then suddenly every single sound that I hear has that same filter as if you were within the regeneration field. This has only happened once to me.
Once I get my capture equipment setup, I'll have these recorded and on the tubes for you guys to see.

The weirdest SPOPs glitch that I've seen is tiny enemies holding normal sized guns. Other than that, lots of weird desync issues (AI apparently freezing in place for you, getting close to them and having them teleport somewhere else, things like that). If horrific, unplayable lag is a bug there's plenty of that as well.

Do you have access to the Halo codebase, or would you just be providing re-creation steps for developers?

Does the film file have any sort of debug data associated with it?

I don't have anything to do with that sort of MP stuff, so I'm just going to attach the link to the bug and send it back to whoever assigned it to me. I'm assuming they can plug the film into something and get some data from it, but I really don't know.
